Patented May 12, 1936 UNITED STATES PATENT OFFICE 2,040,268 HAIR DRYING APPARATUS Harvey L. Orton, Akron, Ohio Application February 3, 1932, 'sag i no. 590,112 2Claims. (01. 34-26) The present invention relates to a hair drying apparatus, primarily intended for use in beauty parlors, and comprehends a construction whereby a number of persons can be attended to at the same time.

Accordingly, the invention provides a plurality of head receiving hoods into which hot air is admitted for the hair drying operation, each hood being associated with inlet and outlet pipes through which the air passes by suction.

In carrying out the invention each hood is especially constructed and equipped with a valve for regulating the flow of heated air into the hood, either at the top whom a point adjacent the bottom thereof.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming partof this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 7 is a section showing the cut ofi position of the valve. V

Figure 8 is a bottom plan view thereof.

Figure 9 is a section on line 9--9 of Figure 3.

The apparatus essentially embodies a casing l0 in which the air employed is heated in any suitof this construction able manner and conveyed therefrom through a sectional pipe l I. There are a plurality of these pipes all arranged in spaced horizontal relation and lead from the top of the casing H) as illustrated. The pipes ll successively vary in length as shown in Figure 2 thereby locating the head receiving hoods supported by the outer ends of these pipes in spaced relation, so that a number of persons can be attended to at the same time. Each hood is also provided with a sectional return pipe l2, which is preferably arranged directly beneath its pipe ll, while all of the return pipes l2 communicate with the casing l0 through a manifold l3. The manifold is equipped with a suction fan of any suitable type indicated generally at I4 and driven from a motor l5. By virtue the heated air flowing to 2| into the chamber tion of each hood is drawn therefrom by suction and returned to the casing 10.

Arranged between the sections of the respective pipes II and I2 for each hood is a valve casing IS in which operates a suitable valve for both regulating the flow of heated air to the particular hood, as well as to control the admission of such air thereinto either at the top or adjacent the bottom of the hood.

For this purpose each hood is of special construction, including spaced inner and outer walls l1 and l8 respectively defining an air receiving chamber l9 by the intervening space therebetween. These walls are connected at their lower ends by a wall 20 which closes the chamber at this end. The wall I! is provided with a series of openings 2| adjacent its lower edge through which communication is established between the hood proper and the chamber IS. The outer wall I8 is formed with a neck 22 arranged in spaced r relation about the adjacent section II which is connected with the inner top of the hood. The neck 22 forms part of an annular chamber 23 connected with the adjacent section of the pipe l2. By proper adjustment of the valve, to' be hereinafter described, heated air can be conveyed directly into the top of the hood through the pipe ll, under which circumstances the air passes downwardly through the hair and concentric of the pipe wall at the H! from where it passes through the chamber 22intothe adjacent seethe return pipe l2. When used in this manner, the heated air is directed on the top of the head of the person wearing the hood, and

of course works its way to-the scalp. However, the hair can be more dried by intermittently directing the heated air close to the scalp and allow such air to work its way up through the hair before leaving the hood.

Consequently by adjusting the valve above re-.

ferred to, the heated air can be conveyed to the chamber 23 through pipe 12, from where it passes into chamber l9, escapingthrough openings 2| into 'the hood proper adjacent the lower end thereof. As this air passes upwardly through the hair it flows from the hood through the adjacent section of pipe II, thence through the valve into the return pipe l2.

The valve can vary in construction for the purposes above stated, but, as shown, embodies a hollow rotatable cylinder 24 mounted in the casing Hi. This valve cylinder is provided adjacent its upper end with three openings equidistantly spaced apart in the same horizontal escapes through openings 25, 26 and 2! effectively and quickly.

plane, while it is also provided with an opening 28 adjacent its lower end. Located within the valve cylinder adjacent its lower end and at a right angle to the opening 28 is a tube 29, the latter opening at diametrically opposite sides of the valve cylinder. Arranged above this tube 29 is a curved tube 30 disposed at a right angle to the tube 29, with one end opening at one side of the valve cylinder adjacent the bottom thereof, while its other end opens at the opposite side of the cylinder adjacent the top thereof. A valve operating rod 3| depends beneath the valve casing l6 and is provided with an indicating finger 32 to indicate the position of the valve and coperate with stop pins 33.

In practice, when the valve is positioned as illustrated in Figure 3, the opening 26 communicates with one section of the inlet pipe I l to admit heated air into the valve cylinder, but as the tube 30 occupies a position to prohibit the passage of this air through the other section of the pipe II, the air is forced to pass through the lower opening 28 into the adjacent section of the pipe l2. The air is thus delivered into the chamber 23 which communicates with the chamber l9 and finally enters the hood from points adja cent the bottom thereof through the openings 2|. As stated, this use of the apparatus directs the heated air close to the scalp and allows the air to flow upwardly through the hair, and pass from the hood through the adjacent section of pipe I I. As shown in Figure 3, this section of the pipe communicates with the curved tube 33 which delivers the air to the return pipe I 2.

By rotating the valve cylinder one quarter of a turn to the right, from the position it occupies in Figure 3, it assumes the position illustrated in Figure 4. In this View it will be noted that openings 25 and 21 of the valve cylinder establishes communication between the respective pipe sections ll, so that the heated air will pass through these pipe sections directly into the top of the hood. At the same time tube 29 assumes a position to establish communication between the respective sections of pipe l2 so that after the heated air escapes from the hood through openings 2! into chamber I9, it enters the return pipe and is conveyed to the casing ID by suction. By shifting the valve cylinder to the position it occupies in Figure 9 all communication is cut off between the sections of pipes II and I2 respectively. The apparatus can be economically operated and easily manipulated, and by virtue of its construction a number of persons can be attended to at the same time and the hair more effectively and quickly dried than by use of present day methods.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein illustrated or described and that such changes may be resorted to when desired as fall Within the scope of what is claimed.
